Grey Silverfish

Grey silverfish prevention relies on eliminating moisture and denying access to storage areas where starches and cellulose accumulate, with attention to the warmer, drier enclosed spaces this species favours. Ventilation is critical in Australian homes — roof voids require ridge or soffit vents to reduce humidity and prevent stagnant air (common in Federation eaves and timber-frame weatherboard cavities); subfloors benefit from increased under-house venting or smart vents to maintain airflow year-round. Seal all cracks and gaps in walls, around picture-frame hangings, behind skirting boards, and behind plumbing penetrations with silicone caulk or foam sealant; grey silverfish are smaller than common silverfish and exploit very tight spaces. Store documents, photographs, textiles, and old books in sealed plastic containers rather than cardboard boxes (which retain moisture and provide food). Declutter dark cupboards and wardrobes — grey silverfish thrive in stacked, undisturbed areas. Use sealed plastic wardrobe dehumidifiers (rechargeable or silica-based) in enclosed storage spaces. For valuable archives or collections, maintain indoor humidity below 50% using a household dehumidifier; silverfish eggs fail to hatch below 50% RH.
